I'm just getting started with my survival garden right now.
Sue - thanks for the comments about seeds on another thread. Also, I like the idea of sweet potatoes. Don't know if they'll work in my climate zone, but I'll check.

One thing that I have thought about adding to my survival garden are a few edible wild plants (native plants) that are not recognizable as common "vegetables". It's always possible that hungry people could invade my backyard and pull up some of the vege's. I don't expect that kind of incident under any normal circumstances, but it might happen in a disaster zone. So it occurred to me that growing a few edible wild plants might be a good back-up strategy - since thieves are not likely to recognize them as an obvious food source.

cheers,
